To all whom it may concern:

Be it known that I, GEORGE V. Tnoor, a citizen of the United States,residing at 'NmvBritain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inBuckles, of

"for instance in connectionwith a belt to hold the same-closed. \Nhileas will be in ferred the belt equipped with the buckle is primarilyintended for human wear, I am in no sense restricted in this particular,be cause it can be employed in the art of harness and in' other ways.Among the primary objects of-the invention is the provision of a bucklewhich can be easily and inexpensively made and which has means of apositive and certain character for securely preventing accidentalmovementof the cooperating belt yersely of itself, so thatlin 'efiectthe-active with respect to the buckle.

In the drawings accompanying and forming part of the presentspecification I have shown in detail one convenient form of embodimentof the invention which to enable those skilled in the art to practisethe invention will be set forth fully in the following description. I amnot necessarily restricted to this particular disclosure; I may departtherefrom inseveral respects within the scope of the invention definedby the claim following said description.

Referring to said drawings:

Figure 1 is a face view of a belt equipped with a buckle involving theinvention.

Fig. 2 is a side elevation,

Fig. 3 a longitudinal section, and

Fig. 4t an inside face view of the same.

Like characters refer to like parts throughout the several views.

As will be clear the buckle may be utilized in a variety of differentways, for in,- stance as shown in connection with a belt such as 2.Associated with this belt, band or strap 2 is a buckle such as thatdenoted in a general way by 3. The belt or strap may be made of anysuitable material such as leather, while the buckle can I find beadvantageously made from sheet metal stock.

The buckle includes in its structure a body piece or section such asthat denoted in a general way by 4:. This body piece or section in turncomprises asomewhat elon- BUCKLE.

Specification of Letters Patent.

Patented Dec.;2,a1919.

Application filed August 20, 1918. Serial No. 250,650.

gated foundation portion 5 longitudinally arched, the concave surfacebeing on the inner side and the convex on the outer side.

The lateral parts of this foundation portion 5 are provided withlongitudinal flanges 6 in p rallelism with each other and integral asshown with the foundation portion 5.

i The said side flanges 6 in turn are provided practically centrally oftheir length-with the inwardly extending-ears or' lugs 7 havingperforations as 8 which provides for the flexible mounting of a clampingor'tongue I unembersuch as thatdenoted in a general way'by 9. Y

The clamping ortongue memlber may within certain respects vary, althoughthat shown and now to bedescribed answers my 'main or mounting portionas 10- which is practically fiat and a clamping portion 11 whichis'somewhat arched or bowed transsurface of the clamping or bindingportion can really functlon as a cam. This clamping or binding portion11 as shown is mounted with the main or mounting portion 10 by a bowedconnecting portion 12.

from which as will be clear the said clamping or tongue member can beeasily and quickly made in one piece. As shown the main or mountingportion 10 has on OPPO. site ends between its inner and outer extremes,the coincident lateral extensions or pivots 13, which although they areof rectangular shape, enter the circular openings or perforations 8 towhich I have already referred. The width of these lateral extensions orpivots 13 is a trifle less than-the diameter of said openings orperforations, so as to provide for the necessary turning movement of theclamping or tongue memher 9. This clamping or tongue member can beobviously formed by doubling sheet stock on itself in such way as tosecure the necessary finished article. As a matter of fact the tonguemember itself can be blanked as to all its portions from sheet stock.The clamping or binding portion 11 of the tongue member is peripherallyroughened as at 14:, in view of which said active portion can obtain asubstantial hold upon a belt or strap such as 2 in the manner I willhereinafter describe.

Gne end of the belt or strap is relatively curing the permanentconnection.

permanently connected with the buckle 3, the other end being capable ofseparable or detachable association therewith in the man- 'ner' which Iwill hereinafter describe. I

will now set forth the means shown fog1 seonnected with one end of thebelt or strap 2 is a terminal as 1-5 which may be of sheet metal. Thisterminal has at its forward portion the eye 16 adapted to flexibly fit v7 around the pivot 17 at the-rear of the main or mounting portion 10. Inview of this circumstance it will be clear that the terminal 15 and theclamping or tongue member 9 canbe freely moved with respect to eachother. 1

It'will be supposed that the parts, except the free end of th belt orstrap are ,connected up as shown in the several views, and that theclamping member or tongue 9 is in its releasing position. When in thisposition it stands practically at right angles to thefoundation portionof the buckle. In view'of this circumstance it becomes a F simple matterto slip the freeportion of J the belt or strap alongthe inner surface ofthe foundation portion 5 between the flanges 6 thereof. Wlien this isdone the two endportions of the strap will be relai tively movedoppositely and on such motion {the terminal will be moved relatiVelyto:ward the. left or outwardly, and will as a consequence swingthe rearpart of the main or mounting portion 10 toward the foundation portion 5,in view "of which circumstance the clamping, binding or cam portion 11will bite into the free; end portion of the strap or belt and will pressthe same sub stantially against the foundation portion 5,

the greater the pullv the greater being :the

pressure ofthe clamping portionupon the free end portion of the strap.

What I claim is:

A buckle comprising ,a body having a foundation Jiece furnished withside flanges" to receiveetween them a strap; a sheet metal memberliaving a fiat mountingv portion and a transversely bowed cam portionbowed cam portion'forming a continuation of th mounting-"portion and itsrear end being adjacent to the rear end of the mount ing portion, themounting portion being integral with the mounting portion the p providedwith lateral integral ,pivots an'd the flanges being provided withearshaving openings to receive the respective pivots,

the cam portion being roughened and en
